General comments

Is limited to Sage but seems to do the job very efficiently. Main
hesitancy against signing up is the fact that it does not handle
line items and there is no trial system and going with the system
involves a minimum 12 month commitment, along with installation and
training time and costs, whereas other comparable systems are
available on a trial and do not involve such an upfront commitment.
One nice thing is that you can have it set up Sage supplier
accounts on the fly.
